Hi all,
I thought a code such that the only fixed (constant) value is the number of
members to enter. It works but I am not sure if I am using correctly the
initialization of the multidimensional array.
In a first step I Initialize the first dimension of the array:
int numberOfMembers = 3;
String[][] arrayOfNames= new String[numberOfMembers][];
In a second stage I ask for the full names of each member (up to
numberOfMembers) and then I initialize the second dimension of the
multidimensional array (and here is where I am not sure if it is valid to
do):
for (int i= 0; i< arrayOfNames.length; i++) {
arrayOfNames[i] = new
String(JOptionPane.showInputDialog(String.format("Member #%d, enter your
full name, please", i+1))).split(" ");
}
In a third stage to find the owner of the longest first name:
int longestFirstNameOwner= 0;
int longestFirstNameLength= 0;
for (int i= 0; i<arrayOfNames.length; i++){
if (arrayOfNames[i].length > 0) {
if (arrayOfNames[i][0].length() >
longestFirstNameLength){
longestFirstNameLength= arrayOfNames[i][0].length();
longestFirstNameOwner= i;
}
}
}
This code works well. If numberOfMembers where a parameter it will be
possible to find the longest first name of any number of people without
modifying this code. But I still have a doubt, if it is valid to initialize
the miltidimensional array in the way I did.
Thanks averibody
